Definitions

  • the invention relates to a liquid supply device for a printing machine cleaning device for cleaning cylinders and rollers of printing machines, in particular of offset printing machines.
  • a liquid supply device of this type is known from DE 20 2004 006 534 U1.
  • the invention aims to solve the problem of providing a low-cost and functionally reliable supply device. This object is achieved according to the invention by the features of claim 1.
  • FIG. 1 is a schematic representation of a liquid supply device according to the invention.
  • the liquid may be fresh water, for example tap water from the local water supply network, or another washing liquid or solvent or a mixture or emulsion of two or more of the aforementioned substances.
  • the liquid supply device comprises an intermediate container 2, which is closed pressure-tight. Furthermore, a vacuum cleaner 4 is provided, for example in the form of an injector or preferably ejector.
  • An air valve assembly 6 includes a controllably switchable first valve 8 in a first compressed air path 10 between a compressed air source 12 and a compressed air inlet 14 of the vacuum cleaner 4, a controllably switchable second valve 16 in a second compressed air path 18 between the compressed air source 12 and the intermediate container 2, and a controllable switchable third valve 20 in a third compressed air path 22 between the intermediate container 2 and a suction air inlet 24 of the vacuum cleaner 4.
  • All or some of the valves of the compressed air valve assembly 6 may be individual valves or part of a valve block having the function of multiple valves.
  • the second compressed air path 18 and the third compressed air path 22 can each be separated or in fluid communication with the interior of the intermediate container 2 via a common connection line 26.
  • the compressed air source 12 may be a compressed air connection element for connection to an air compressor or to a compressed air supply network or to a compressed air storage tank, either directly or via a pressure regulator.
  • the compressed air source 12 includes an air compressor 28 and a pressure regulator 30 at the outlet of the air compressor.
  • z. B. upstream or downstream of a pressure regulator 30, a compressed air storage tank 32 may be provided, from which for a short time more compressed air can be removed than from the air compressor 28th
  • the vacuum cleaner 4 further has an air outlet 25 for discharging air 27 into the outside atmosphere, preferably via a filter or moisture separator 29.
  • a remplisstiksauslassweg 42 from the intermediate container 2 includes a liquid valve assembly 44 which includes at least one switchable remplisstechniksabgabeventil 46, 48, 50, etc., the valve outlet side 47 and 49 and 51 is connected via a fluid line to the cleaning device.
  • the liquid valve assembly 44 includes a liquid dispensing valve 48, the outlet side 49 of which is connected via a liquid line 52 to a spray device 54 of a cleaning device 56 for spraying liquid onto a cylinder 58 (or a roller, such as a paint roller).
  • the cleaning device may include a squeegee 60 for doctoring the liquid softened paint from the surface of the cylinder or roller 58. Further, as another example, FIG.
  • FIG. 1 shows a discharge line 62 through which the outlet side 51 of the liquid discharge valve 50 is connected to a nozzle device 64 for spraying liquid onto a wash cloth 66 of a cleaning device 68.
  • the washing cloth 66 is engageable with the circumference of a cylinder 70 or the circumference of a roller to clean its peripheral surface.
  • All or some of the valves of the liquid valve assembly 44 may be individual valves or part of a valve block having the function of multiple valves.
  • An electrical control device 72 shown schematically in Fig. 1 is used to switch the switchable valves such that for sucking liquid 36 from the reservoir 34 into the intermediate container 2, the first valve 8 and the third valve 20 and the remindströmsperrventil 40 are open, whereas the second valve 16 and the liquid dispensing valve assembly 44 are closed, and that for dispensing liquid 36 from the intermediate container 2 to a cleaning device 56 or 68, the first valve 8 and the third valve 20 and the remindströmsperrventil 40 are closed, whereas, the second valve 16 and at least one of the liquid dispensing valves 46, 48 and / or 50 of the liquid dispensing valve assembly 44 are open.
  • the remindströmsperrventil 40 is a check valve which opens by the differential pressure between its input and its output only in the direction from the reservoir 34 to the intermediate container 2, but automatically closes at a pressure in the opposite direction.
  • the remindströmsperrventil 40 may be controllably switchable by the controller 72 valve.
  • the intermediate container 2 has such a size that its liquid supply is sufficient for at least one washing operation in the printing press. For example, its capacity is about two liters.
  • the intermediate container 2 is preferably provided with a level sensor 74 to end the filling operation of the intermediate container 2 when the liquid level reaches the level sensor 74.
  • the level sensor 74 may be a float switch or magnetic or electromagnetic or capacitive or other sensor or switch connected to the signal transmission controller 72.
  • the control device 72 may be designed such that a filling of the intermediate container 2 and / or the supply of liquid from the intermediate container 2 to the printing machine for a washing process can be started manually. According to another embodiment, however, it can also be provided that the filling and / or the liquid supply to the printing machine is automatically triggered by a printing machine control, which is connected to the electrical control 72 for this purpose.
  • the reservoir 34 may be of any type, for example, a standard container in which washing liquid manufacturers supply the washing liquid to the customer, or a custom designed container.
  • a supply cabinet 80 is provided, in which at least the intermediate container 2, the vacuum cleaner 4 and the compressed air valve assembly 6 are housed.
  • the reservoir 34 air compressor 28, pressure regulator 30, compressed air storage tank 32, electrical control device 72 and / or the liquid valve assembly 44.
  • the reservoir 34 especially if it is a larger tank, and / or the air compressor 28, pressure regulator 30 and / or the compressed air storage tank 32 may be disposed outside of the supply cabinet 80.
  • the liquid valve assembly 44 may be housed in the supply cabinet 80 or preferably provided on a printing press.
